Belzona 5851 (HA-Barrier)

A heat-activated epoxy coating for in-situ application to hot metal surfaces with minimal preparation to protect against corrosion.

A solvent-free, single-component epoxy coating, which cures in contact with hot surfaces and is designed to prevent or protect metal from corrosion under insulation (CUI). Belzona 5851 (HA-Barrier) can be easily applied by brush and does not require any weighing or mixing.

This heat-activated material can be applied directly onto hot surfaces (70-150°C / 158-302°F) with minimal surface preparation, avoiding production downtime. Once cured, it provides outstanding corrosion protection. Also available is Belzona 1251 (HA-Barrier), a heat-activated epoxy repair composite which can be used in fill pitting and bond equipment among other applications.

Key benefits:

In-situ application to live equipment operating at high temperature with minimal surface preparation

Single pack system, no weighing or mixing required

Reduced health and safety risks as it is solvent-free and no hot work is required
